Audio-Visual Class-Incremental Learning

1 code implementation ICCV 2023 Weiguo Pian, Shentong Mo, Yunhui Guo, Yapeng Tian

We demonstrate that joint audio-visual modeling can improve class-incremental learning, but current methods fail to preserve semantic similarity between audio and visual features as incremental step grows.

Predicting Patch Correctness Based on the Similarity of Failing Test Cases

1 code implementation28 Jul 2021 Haoye Tian, Yinghua Li, Weiguo Pian, Abdoul Kader Kaboré, Kui Liu, Andrew Habib, Jacques Klein, Tegawendé F. Bissyande

Then, after collecting a large dataset of 1278 plausible patches (written by developers or generated by some 32 APR tools), we use BATS to predict correctness: BATS achieves an AUC between 0. 557 to 0. 718 and a recall between 0. 562 and 0. 854 in identifying correct patches.

STDI-Net: Spatial-Temporal Network with Dynamic Interval Mapping for Bike Sharing Demand Prediction

no code implementations7 Jun 2020 Weiguo Pian, Yingbo Wu, Ziyi Kou

As an economical and healthy mode of shared transportation, Bike Sharing System (BSS) develops quickly in many big cities.

Spatial-Temporal Dynamic Graph Attention Networks for Ride-hailing Demand Prediction

no code implementations7 Jun 2020 Weiguo Pian, Yingbo Wu, Xiangmou Qu, Junpeng Cai, Ziyi Kou

However, existing GCN-based ride-hailing demand prediction methods only assign the same importance to different neighbor regions, and maintain a fixed graph structure with static spatial relationships throughout the timeline when extracting the irregular non-Euclidean spatial correlations.
